Should be able to run the fill hose from from the center locker bag if it has three ports, through pass through under the helm through the hump then up to the right leg of the ibs, with the reversible pumps and the vents Y together with a check valve , it should drain fine.

Thanks, I talked to Spencer and wakemakers and he said the same thing. He made a list for me a one item was a vent hose to run from my center bag to the ibs. I think the vent already runs to the thru hull vent so I dont think I would need 10 feet of it. Does it matter where I split my center bag fill line?

You don't need to split your center bag fill line. You just take the center bag vent line off of the thru hull vent and hook it up to the right leg of the IBS. You need 10 feet of new ballast hose and a check valve to go from the nose of the IBS back to the thru hull vent. Pretty simple and fully automatic.

So to make sure I understand this correctly, you just remove the center bag vent line and connect it to the IBS so once the center bag is full it will then send water forward and fill the IBS. The extra 10 feet of hose then runs from the IBS back to the thru hull vent. You need to also put a check valve in the vent line between the IBS and the thru hull vent. Do I have it right? Also, what exactly does the check valve do? Thanks.

You move the old vent line from the center bag to the right leg vent on the IBS.

The new 10 feet of line goes from where the vent used to connect on the center bag to the fill port on the IBS. I used the larger hose for this, whatever the standard fill hose size is (I can't remember the size). The vent size is smaller.

The check valve gets added on the vent line close to the through hull fitting. It's basically a floating ball valve that allows air and water out, but when you start to drain closes off so air can't get sucked back into the bag creating a drain/suction action. I added the check valves on all my vent lines so my bags would drain better.
